Please correct me if I am wrong: you've got a "pure" DTS-Express stream, and LAV Splitter does not support 'containerless' DTS Express --- you would need to wrap it in an .m2ts file, at least. You might add a .WAV header to the stream as well.

yes, a pure stream just with the .dts file extension.

I tried muxing that stream into a m2ts file with tsmuxer, but the result is still the same. cannot find or select the file with mpc-hc

I also cant play the .m2ts file with the dts express track itself, mpc-hc then says I cannot render the file. tried with mpc internal LAV audio and standalone LAV audio, with the dtsdecoderdll.dll placed in those directories

^ Make sure the checkbox for "Secondary (audio)" is ticked in the TSmuxer GUI.

You said "menu"?

Control + O, select the video file, then choose the "dub" file.

(I'm still using MPC-HC Lite, and I presume/hope the "LAVved" MPC-HC still supports the same trick).

P.S.: As a last resort, you will have to add a proper .WAV header to the DTSX stream:

that field is greyed out for me.

well, I meant right click into the picture and then either audio or filters + audio switcher or filters + lav audio. cant see the dts express track anywhere there.

didnt work with ctrl + o and then the dub file either. only can see the standard 5.1 track of that movie.

I added a P.S. to my previous post.

Yes, it seems TSmuxer has something against 24-bit DTS Express

P.S.:

that field is greyed out for me.

Ooops, by using TSmuxer.exe, not the GUI, it's possible to add manually the secondary switch to the .META file.

thanks for the link to the waveheader. however I dont understand how to edit it. Do I edit the hex field or the text field? and what If the numbers I need exceed the space of the symbols? (e.g. \\\\ for number of bytes arent enough for that many digits I need to express the size in bytes). the track I have is a 1.0 48kHz 96kbps 24-bit track with a size of 80.674.816 bytes

I are confused

[filler56789]

Before going into more complications,
please give a try to my last P.S.

[Thunderbolt8]

alright, the muxing worked. I can now select the track in mpc-hc. however I still cannot play the track. whenever I switch to it, the video just stops and doesnt continue any more -.-

do I maybe need a certain version of arcsoft here? currenly I am using 1.1.0.1

[filler56789]

Versions 1.1.0.8 and 1.1.0.9 support mono DTS Express.

1.1.0.8 converts mono to stereo, whereas 1.1.0.9 redirects the front center channel to the front left channel

[Thunderbolt8]

its working now with 1.1.0.8. thanks!

[filler56789]

Yeah, about time!

Merry Christmas.

Santa Nevcairiel, my Christmas wish is for a way to display the LAV Audio Input/Output details as shown on the Status properties on the screen much like madVR displays stats when ^J is hit.

I use JRiver with LAV and madVR. This would be an awesome addition.

Thanks and all the best for the New Year!

[nevcairiel]

How would the audio decoder ever show stuff on screen? Just look at the status panel, that's what its for.

If a player wanted to, it could access this information and show it on screen, but LAV will never do that.

[Boltron]

I know the player needs to perform the display but it all starts by making the info available to the player. So my first stop was to see if LAV can provide the details by perhaps an API call. Does this already exist?

Thanks.

Can you confirm that in .mkv sample below lav splitter doesn't detect subtitles at all?
Mkvinfo and mediainfo reported that two subtitle .srt strteams presented...

This occurs in LAVFilters because "Track FlagEnabled" is set to false. Which is defined as 'Set if the track is usable.' in the MKV spec. You can fix this with either MKVToolNix Header Editor, or by demuxing the subtitles and muxing them in again.

How much LAV's literal interpretation of this flag makes sense to the end-user is somewhat debatable though, since why would you mux a subtitle track which could never be displayed during playback? The real question is how this flag was originally set, was it user error or something else? Which mkvmerge version was the original untrimmed version of that video muxed with?

Granted, Haali Splitter still makes such tracks available even when that flag is set. If this encode was originally muxed way back in early April 2011 when the Blu-ray was released, Haali was probably the only thing it was ever tested on. Though I suspect this is a somewhat more recent behavior in LAV Filters as a result of him refactoring, so if this was an older encode it may have even worked with LAV way back then.

Thanks for pointing me out.
I think this was user error.

Nev:
I got this MKV+VC1 clip that causes an access violation in ntdll.dll when trying to remove the 'LAV Video Decoder' filter from the graph.
It doesn't always throw the error, perhaps some sort of race condition? Hardware acceleration is set to 'none'.

Switching the video decoder to Microsoft's DMO and the error isn't triggered anymore.
